Setup
1. Battery Installation

- Insert two AA alkaline batteries (not included) into the compartment, ensuring correct polarity (+/-).
- Securely screw the lower part of the microphone body back into place.
The microphone provides up to 10 hours of continuous use with fresh AA alkaline batteries.
2. Pairing with D-Series Wireless System
The HT-450 microphone is designed to seamlessly connect with Nady D-Series wireless receivers. Refer to your D-Series receiver's manual for specific pairing instructions. Generally, the process involves:
- Powering on both the microphone and the receiver.
- Selecting a clear channel on the receiver.
- Initiating the sync function on the receiver, then aligning the microphone's IR sensor (if applicable) with the receiver's IR transmitter to establish a connection.
- Confirming successful pairing via the receiver's display and the microphone's LCD.
Operating Instructions
1. Power On/Off
- To power on, press and hold the power button located on the microphone body until the LCD illuminates.
- To power off, press and hold the power button again until the LCD display turns off.
2. LCD Display
The backlit LCD provides essential information, including:
- Battery Level: Indicates the remaining battery life. Replace batteries when the indicator is low.
- Channel Number: Displays the currently selected operating channel.
- Signal Strength: Shows the strength of the wireless connection to the receiver.
3. Channel Selection
The HT-450 offers 200 total channels to ensure clear transmission. Channel selection is typically managed through the paired D-Series receiver. Once a channel is selected on the receiver, the microphone will sync to that channel during the pairing process. If interference occurs, select a different channel on your receiver and re-sync the microphone.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the microphone body. Do not use liquid cleaners or solvents.
- Storage: Store the microphone in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
